Maybe I'm wrong, but I think there is a misunderstanding here. There would only be one library, but each machine would have a separate database. Correct? That's how I'm doing it with me and my son. I only have one library, but I sync the database in the living room with my bedroom, so both have the same "marked as watched" shows. The one in my sons room does not sync, he has his own database and his shows only mark watched on his machine. There is only one library, but separate databases. I use an auto update addon on his machine and the one in the living room, so when a show is added to the library, the databases automatically update on each. Easy, I don't have to do anything. Changing the file structure though, how often do you do that? and why?

I am assuming the by library, we mean the actual downloaded shows, and by database, the list of whats on the server.
